The Sunpak® Models S25 & S34 are outdoor rated heaters available for use with natural or propane gas. These heaters can be either wall or ceiling mounted. The optional mounting kit allows this heater to be mounted from above keeping the patio deck free and clear. Heat coverage varies depending on the wind exposure on patio. The average spacing between the heaters is 10 feet apart.

Sunpak® comes with a 24 VAC spark ignition system which includes flame monitoring through flame rectification. All Sunpak Heaters require an external 24 VAC source. As an unvented gas heater, Sunpak® heaters need a continuous supply of fresh air and proper ventilation of combustion gases to operate safely. This heater is not suitable for inside residences and other confined areas where the operational and safety requirements of this heater cannot be met. Refer to heater instructions, available online or from manufacturer for complete information.

The Sunpak® heater design offers a slim profile which works well in a wide variety of patio settings. Sunpak® heaters are available in either black powder coat or a 304 stainless steel finish.
